Our heating system and thermostat are approx 1 year old. It is set at 60 at night, however, sometimes, it is cranking out heat above 60 and says "recovery". Why is this happening and how do I prevent it?
Thanks!

The thermostat has adaptive intelligent recovery. It would take forever to type all the info about that. Please referr to your owners/install manual. It is clearly listed as to what it does. Is it normal. YES.

Type this into Google.

adaptive intelligent recovery

But if you don't want it to do this - can it be stopped? Our heating bill doubled last month and I think this is the problem... why would this feature cause it to override the programming?

Thanks for all help - Kathy:confused:

So I googled the adaptive intelligent recovery and if I understand the feature- it's starting heating the house at early so it's at temp by the time the programmed start time hits... but that's what we did with the start time - so basically we have to set the start times later to accommodate the systems calculations??

Sorry - I've never noticed this working this way before - all help is truly appreciated. Kathy

Thanks for the info... the prob is that I've caught it on at around 4am and our thermostat wasn't set to reach 65 until 7am... the screen on the thermostat says "recovery"... I think my bills have dbld because of this also!

You have to choose between comfort or less energy usage.
On some of the models you can stop the recovery feature and wake up to a very cold house if you want.

If you are using this type on thermostat on a heat pump your bills will go up because it will kick in the eletric resistance heat on some models.

Set back thermostats should not be used on heat pumps at all in my opinion.

Thanks for the information. At least I'm not going to go crazy wondering what's wrong with the settings.

This feature is a joke. Do a search on the internet and you will multiple people with problems using this thermostat. Our's was scheduled for winter at 62 at night, with a 6:45 AM setting of 71. I would routinely wake up roasting in bed at 5AM to find the thermostat running at 71 with 'In Recovery' displayed. Just for testing purposes one night I got out of bed and watched it take the heat from 62 to 70 degrees within 20 minutes

As for choosing between comfort and energy savings... with this thermostat you are getting neither.

I have a tendency to agree with JeffG. What is so "Intelligent" about this override feature, and what is the purpose of my judgment - with my customized personal settings - if this feature is going to override my settings EVERY night!!

The adaptive recovery feature does exactly what it is supposed to do. I have been using Honeywells system for years and have no complaints since I know what its features are and how it works. If a heating unit is properly sized and not oversized during very cold weather it may take 2 or 3 hours to bring the temperature from 50 degrees to 70 degrees. I do not want to come home or wake up to 50 degrees and I do not want to have to out guess the heat loss of the structure to program so the Honeywell does it all for me. The recovery design does take about 72 hours to actually calculate the heat loss of the home and that time does not include any playing with the thermostat settings. It is best to set it and leave it alone so the intelligent feature of the thermostat has time to calculate.

NO set back thermostat will really work well with a heat pump system so if you are using one on a heat pump you are better off without it.

Guys (and Gals) this is all really great conversation, but I know that there's supposed to be a way to remove the Adaptive Recovery Feature and allow the thermostat to use conventional methods. In the owner's manual it says to consult a heating specialist to have it set to conventional, since Adaptive Recovery is the default. What I want to know is how can I save myself from having to call a repair man and the associated costs and do this myself? Can anyone provide guidance how to change this to Conventional?

If you have the INSTALLER manual for the thermostat it will tell you how to get into the installer program. Turning the AR on or off will usually be one of the settings in there. If you don't KNOW what you are doing in there you could get yourself into a peck of trouble. If you change other settings to the wrong values you can really bollix the system up. Could cost you more in repair bills than you saved by DIY. Don't say you weren't warned. As was said in an earlier post, if your system is designed right and you aren't fiddling with the tstat all the time, the AR should work well. Just don't program an added recovery period into the system yourself. I personally love mine.

SGS1965 · Dec 25, 2009, 09:20 PM

Thanks EPMiller. I don't have the Installer Manual but I'd like to get one to see how difficult this is. Do you know where I can get one? Again, thanks for your reply.

I have a heat pump, Chronotherm IV T8600D, and the Adaptive Intelligent Recovery works reasonably well for me. My problem is the Chronotherm overshoots the target. I have the house set for 65 while I sleep and 69 at 7AM. The Chronotherm is usually close to getting the house to 69 at 7AM. The problem is my Chronotherm then keeps going. Often the house is 71 or 72 by 8AM. This happens most days. The only way I can stop it is by switching the Chronotherm to Off, waiting for the system and blower to stop, then switching the Chronotherm back to Heat.

Download the Installation Manual from the web. It easily describes how to change the adaptive recovery setting to conventional. Page 5 has the "Installer Setup", and page 6 shows the "Installer Setup" number.

I agree with most people - the "intelligent recovery" is anything but! I bought a house two years ago, that had a Honeywell Thermostat model TH4110D1007. The heating/cooling worked fine, under conventional settings, for the first two years. Then last month, for some inexplicable reason, the "recovery" setting started coming on - and always hours before I wanted the house to actually heat up. I'd always had the heat set to come on 30 minutes before we get up in the morning, because that's how long it takes the house to warm up, so we do wake up to a comfortable and warm house (NOT having to "choose between comfort and less energy usage"). But with this smart recovery setting, the heat was roasting me out of bed 2 hours before my alarm clock, and our energy bill was much higher than normal. I finally called Honeywell, and the service technician explained to me that my thermostat model was a professional model, and so they usually wouldn't help me out and that normally I'd need to call the company that installed it. But since it was my first time calling, he helped me anyway and walked me through the steps to disable the intelligent recovery program. It was a long list of steps that required pushing the up and down arrows in a certain order and for a specific amount of time, sometimes simultaneously. Later, I did some further digging and found some pdf owners' manuals online that explain how to disable the recovery feature for a non-professional model. Simply Google "honeywell thermostat troubleshoot recovery" or something to that effect.
